Definitions

  • the invention relates to a method for producing fiber-reinforced concrete components, in which a lattice-like laid scrim is incorporated into cement masses, and to molded parts produced by this method. "Molded parts” are also to be understood here as building material panels.
  • DD-PS 41 435 a method of the type mentioned is known in which glass fiber strands or rods - preferably prestressed - are embedded in concrete.
  • the glass fiber rods should replace the usual metal reinforcement. By soaking them with suitable resins, the glass fiber rods are protected against chemical attacks and at the same time made dimensionally stable.
  • quartz sand is sprinkled on the soaked bars, or glass fiber strands soaked in resin are wrapped in a spiral.
  • the glass fiber rods merely function as a steel bar take over the reinforcement and where the quartz grains scattered on the glass fiber rods only create the connection between concrete and glass fiber rod, there is no multidirectional elastic reinforcement grid.
  • a reinforcement element for concrete made of glass fiber reinforced plastics is known, in which a grain of quartz powder and fine chippings is attached to the reinforcement element to increase the adhesive strength between the reinforcement element and the concrete, or the reinforcement element is spirally wrapped with profiled strips. Even when using reinforcement elements treated in this way, flexible multidirectional reinforcement grids are not created.
  • asbestos is used as the reinforcing fiber.
  • Cement is used here as a hydraulic binder to process the relatively fine fibers, which are often only a few millimeters long. The process is reminiscent of the manufacture of cardboards. Of a thin cement paste form on a drum fine asbestos cement fleece e, running one above the other, until the desired thickness is obtained. They can then be removed and compressed under pressure.
  • This method can also be successfully used when large amounts of water are added to the asbestos-cement mixture.
  • the binding power of the cement is preserved through the close hydraulic combination with mineral fibers.
  • DE-OS 2 409 231 discloses a process for the production of shaped articles solidified by inorganic binders and reinforced by mineral fibers.
  • surface-area reinforcement mats impregnated with binder glue or mortar which consist of artificial mineral fibers, are placed one above the other and / or next to one another in the fresh, non-set state until the desired reinforcement is achieved.
  • binder glue or mortar which consist of artificial mineral fibers
  • shear-resistant connections of the different fiber mats can be achieved by sewing with mineral fiber bundles.
  • the known method cannot be used to create reinforcement with reinforcement fibers that are perpendicular or transverse to the mats. This means that - due to the nature of the known method - no multidirectional reinforcement with a high degree of fineness can be created.
  • fibers or tissue chips are arranged on this thread structure.
  • the laid scrim can consist of endless fiber filaments or. consist of staple fiber yarns.
  • the fibers can consist of the same materials or of completely different types of fibers if special properties of the concrete are to be achieved. Their length can also be varied. It can range from a few millimeters to many centimeters.
  • some parameters of the reinforcement structure must of course be coordinated with one another: for example, the spacing of the threads of the scrim and the length of the threads on the scrim arranged fibers and their elasticity can be varied.
  • the method is such that the applied fibers experience a multidirectional arrangement, namely in the plane of the thread structure and / or protrude from this plane. If necessary, three-dimensional reinforcement can also be achieved.
  • the product combined from continuous threads and cut fibers remains so open on its surface that it is easily separated from the pulpy cement mass e.g. can be enclosed in an automated process.
  • uncontrolled accumulations of fibers on the scrim are avoided by first providing the scrim with an adhesive and then exposing it to a stream of falling fibers, which then have different, arbitrary orientations on the thread put stuck. Non-stick fibers fall off again. Fiber masses that are difficult to penetrate by cement masses are avoided. According to a different procedure, an air flow can have a supporting effect.
  • Another method variant provides for arranging rollers in order to roughen the fiber pieces lying on the grid and thus to lift fibers or fiber parts out of the plane of this flat structure and then to solidify them with a fixing agent.
  • This can be done easily with a thinly set liquid concrete or with commercially available adhesives e.g. on a plastic basis.
  • the solidification can take place by spraying, by dipping or by doctoring. This method is used in particular when compression of the voluminous reinforcement structure is to be avoided in the subsequent work process.
  • the manufacturing process for the reinforcement structure is not tied to a specific type of fiber.
  • Glass filaments can be used, the high strength of which does not change due to the influences of the cement.
  • synthetic yarns for example made of polypropylene, are also suitable, which above all improve the burst strength of the concrete.
  • a combination of structural steel grids or wire mesh with fibers or fabric chips or fabric strips is also possible or the use of natural fibers, e.g. Sisal. Even those fibers that cannot withstand the aggressive media of the cement are suitable for the lattice structure if the fibers applied have this resistance.
  • the cut fibers or yarns which are intended to supplement the properties of the reinforcement structure, can also be made from the glass fiber type mentioned, from polyamides and other synthetic fibers or from steel fibers or wire consist. It is not important that, for example, a glass fiber laid scrim can only be provided with cut glass fibers and a thread system made of synthetic fibers can only be provided with the same pieces of fiber. With the help of this manufacturing process, it is possible for the first time to incorporate precisely metered mixtures of these fibers with each other into concrete and thus achieve new properties of the products. Another advantage over the known reinforcement methods with fibers results from the fact that partial areas of a component or a plate that are particularly stressed are reinforced.
  • Glass-fiber-reinforced panels can be produced in such a way that they have a very high breaking strength, which allows, for example, nailing.
  • the edge zones of a plate that is nailed can be additionally reinforced using this method.
  • sandwich panels with a hard foam core are mentioned.
  • the rigid foam core can consist, for example, of polystyrene, polyurethane or foamed concrete, foamed concrete in particular being interesting because of its low price. If you bring e.g. A thin layer of cement mortar on polystyrene plates, in which the reinforcement structure described is embedded, creates a stable and stable plate that complements the good thermal insulation properties of the polystyrene through the reinforcement of the strength of the plate surface, without losing the easy processability by woodworking machines.
  • a board made by the method of the invention will preferably be made of cement. But there are also other binders e.g. Plaster in question.
  • the laid scrim according to the invention consists of the longitudinal or warp threads 1 and the transverse or weft threads 2. This scrim was impregnated with pressure sensitive adhesive and then exposed to a stream of fiber parts or fiber chips. The fiber parts 3 adhere to the threads of the scrim with different orientations and form a 'three-dimensional, multidirectional reinforcement structure with this. This is then incorporated into a cement paste using one of the methods already described.
  • FIG. 2 shows a cross section of a building material board produced by the method according to the invention.
  • This consists of an inner carrier layer 10 made of polyurethane foam, on which cement plates 11 reinforced according to the invention are attached on both sides.
  • the polyurethane foam layer is preferably covered with a reinforcement structure consisting of laid scrims and the fiber parts attached to them.
  • liquid cement is sprayed onto the occupied side of the polyurethane foam layer with a nozzle up to a layer thickness of a few millimeters.
  • the thickness of the polyurethane foam layer 10 is approximately one centimeter.
